Does `File.info(string)/File::Info.new(string)` resolve symbolic links?

I'm using Crystal 0.25.0 and File.info(string).symlink? returns false when it should return true in the following sample:

`mkdir -p /tmp/delete`
 Dir.cd "/tmp/delete"
`rm -f b`
`touch a`
`ln -s a b`

puts File.info("b").symlink?.inspect  # false
puts File.info("b").type              # File
puts Process.run("test", "-L b".split).success? # true
puts Process.run("test", "-L a".split).success? # false

It seems to resolve the link. Is this the expected behaviour?

Solution

  • Yes, File.info follows symlinks by default. This is the expected behavior, but you can disable it by passing follow_symlinks: false to the method:

    File.info("b", follow_symlinks: false).symlink? # => true

    This behavior is documented under File.info in the API docs.
